Examples of the components include without limitation steering wheel, brakes, accelerator, lights, and the like. Examples of the autopilot commands include without limitation accelerate, decelerate, turn left or right, signal, and the like.
  • a vehicle equipped with the autopilot processing platform can be referred to as a self-driving vehicle, a driver-less vehicle, an autonomous or semi-autonomous vehicle, or an autopilot vehicle.
  • KR 2017 0081920 A The state of the art is represented by KR 2017 0081920 A .
  • vehicles can transmit data between one another.
  • one vehicle can transmit information about the traffic around the vehicle to another vehicle.
  • This information can include enviromental information such as streetlights, buildings, obstacles, cyclists, or pedestrians that are captured by the sensor of the vehicle.
  • This informaiton can also include information related to the driving actions of the vehicle, e.g., information of speed, acceleration, turning.
  • These data can be used for the recieving vehicle to perform autopilot processing and generate autopilot or semi-autopilot commands for the receiving vehicle.
  • Inter-vehicle data communications can be performed using vehicle-to-vehicle (V2V) communication protocols.
  • V2V refers to communication between any two Intelligent Transportation Service (ITS) capable vehicles.
  • ITS Intelligent Transportation Service
  • V2V enables transport entities, such as vehicles, to obtain and share information regarding their local environment in order to process and share knowledge for more intelligent transport related services or applications, for example, cooperative route planning, cooperative collision warning, or autonomous driving.
  • V2V can refer to services provided to a user equipment for communication supporting vehicle oriented services. Examples of vehicle oriented services include road safety, (transport) traffic efficiency, and other application services.

Therefore, V2V message can be used to convey multimedia content requests, while a different communication technology, e.g., Multimedia Messaging Service (MMS), can be used to transport the requested multimedia content.
  • MMS Multimedia Messaging Service
